Abstract: Sheets of material used in medical devices and filters are disclosed. The sheets may include a fibrous mat including a plurality of microfibers. The microfibers may include a polymer matrix and a plurality of additive particles. The additive particles may include carbon material particles, therapeutic micro particles, and any combination thereof. Medical devices and filters that use the sheets are disclosed. Methods of producing the sheets are also disclosed.

Abstract: The present disclosure describes systems and methods of annealing segment of a reinforcing coil of a catheter shaft. A method includes providing a liner and annealing a segment of a reinforcing wire such that the segment is between two unannealed regions of the reinforcing wire. The method also includes, after annealing the segment of the reinforcing wire, coiling the reinforcing wire over the liner to form a wire frame having a distal portion and a proximal portion. The wire is disposed more densely in the distal portion than in the proximal portion, and the segment of the reinforcing wire that is annealed is at least proximate to the distal portion of the wire frame. The method also includes securing a jacket over the wire frame and the liner.

Abstract: The present disclosure describes systems and methods of forming a continuous reinforced catheter shaft having multiple wire frames. A method includes providing of a first spool having a liner rolled thereon and unrolling at least a portion of the liner from the first spool. The method also includes coiling a reinforcing wire on at least the portion of the liner unrolled from the first spool to form a plurality of coiled wire frames and an interim portion of the reinforcing wire coiled adjacent coiled wire frames. The method also includes securing a jacket over the plurality of coiled wire frames and the interim portion of the reinforcing wire coiled to form a continuous shaft having the plurality of coiled wire frames.

Abstract: Devices and materials are disclosed for collecting breath samples and for testing such samples for the presence of a pathogen, for example the pathogen(s) associated with Coronavirus Disease 2019 (COVID-19). In some embodiments, a collection device can include a tube into which a subject can exhale or cough, and that provides for use of a filter to capture expired sample material. In some embodiments, a sample liquid can be created from the breath sample by addition of an indicator to render a pathogen in the sample readily detectable. In some embodiments, materials are provided for an assay to detect a pathogen in the sample liquid.

Abstract: Elongate medical appliance isolation and cleaning devices and methods are disclosed. The isolation devices provide disposable coverings of the elongate medical appliance, such as an IV pole, to protect the elongate medical appliance from contamination. The cleaning devices provide a tool to clean and disinfect the elongate medical appliance following use.

Abstract: A method of testing a coating on a reflector having a first focal point includes placing a mirror at the first focal point of the reflector and angled to orient with an area on the coating. Electromagnetic (EM) radiation is directed to the mirror which then directs the EM radiation on the area. The EM radiation which is reflected from the coating is collected onto a sensor disposed at a second focal point. The intensity of the EM radiation collected on the sensor is detected.
